This paper is concerned with how to read Aeneas’ Shield in Aeneid 8. For this, I have made some comparisons between Virgil and Livy, in order to answer the questions of how did Virgil symbolize Rome as a ruler of the World. In this regard, I have examined how Virgil combined the Roman History with the idea of imago mundi using ekphrasis-technic. According to my examination, imago mundi in Aeneas’ Shield is not just a kind of mappa mundi, but a political Kosmos which as whole was subject to Imperium Romanorum. Historia Romanorum in Aeneas’ Shield also was not an accumulation on old narratives and historical facts of the Roman People, but was designed and organized planfully as a world history on the basis of fatum-concept. Doing this, I have figured out how Virgil prefigured the Roman Empire and how he provided the image of an Emperor to the Roman readers or audiences through the shield-scene. In this regard, what to emphasize is that Virgil was very meticulous and excellent in word selection and architectural organization of space in the Shield. In description of the Roman Republic history, he used intentionally terms which are important ideas for sustaining res publica like fides, justitia, libertas, concordia, etc. For justifying the rule empire, however, he selected some words like pax, bellum, populi, imperium, etc. This is evident in the following: tu regere imperio populos, Romane, memento (hae tibi erunt artes), pacique imponere morem, parcere subiectis et debellare superbos. (Aeneis, 6. 851-853)
